If you're curious enough you could buy a copy of this EK-KCRSC-FS-001
manual if you can't find a copy online anywhere:
Here's a start:

I found DEC document EK-KCRSC-FS-001 "Remote Services Console: Field
Service Manual." Sometimes I'm sure God is a computer collector.
Local Console Terminal A1
CPU Conole Port A2
Optional to Comm port B1
Connection to modem B2
Now the way it works is it can use the modem from an existing dial-in line
which presumably the customer would already have. So where you would
Console >-------------> Computer
Modem >-----------==> Comm port
Console >---+ R +------> console
| S |
Modem >----+ C +------> comm port
This lets the modem be used to dial in the console or on the comm port when
not remotely diagnosing issues.
Buttons on the front control baud rate, the mapping is:
out out out 300
in out out 1200
out in out 2400
out out in 4800
in in in 9600
Baud T is the terminal and should match the console port setting
Baud M is the modem (1200 baud preferred :-)
The various modes:
REMOTE - modem can dial into the console. Light blinks
when no one is dialed in
REMOTE USER - modem is connected to the comm port
USER PORT - all operation is transparent console and modem
connect "straight through" to the other connector
LOCKOUT - modem can't be used to get to the system.
The dial in line uses the DDCMP protocol to insure data integrity. I'm not
sure what this means in terms of being able to dial it from a PC.
